Abstract
The invention relates to a frictional energy dissipation type buckling-restrained brace, which belongs to the field of seismic control of building structures. The frictional energy dissipation type buckling-restrained brace comprises a restraining member (1), a piston (2) and an energy dissipation core (3). The piston (2) is arranged at the middle of the energy dissipation core (3), the restraining member (1) sleeves the surface of the piston (2), the restraining member (1) is fixed at one end of the energy dissipation core (3) through an end plate (4), and connecting steel plates (5) are arranged at both ends of the energy dissipation core (3). Since the invention arranges the piston in the conventional buckling-restrained brace, the frictional energy dissipation mechanism is introduced. When inter-story displacement takes place in a structure, the energy dissipation core can be plastically deformed to dissipate energy, at the same time, the energy dissipation core and the restraining member shift relatively, the piston fixed on the energy dissipation core and the restraining member move relatively, energy is dissipated by the friction between the piston and the restraining member, and thereby the energy-dissipating capability of the buckling-restrained brace is effectively enhanced.
Description
Technical field:
The present invention relates to the anti-buckling support of a kind of friction energy-dissipating formula, be applicable to the shockproof control of building structure, belong to shockproof control field.
Background technology:
Anti-buckling support is the compressive buckling arranging sleeve pipe constraint support in supports outer, to solve the problem of common support compressive buckling and Hysteresis Behavior difference, is a metalloid surrender type damper.Anti-buckling support has the following advantages: (1) himself bearing capacity is separated with rigidity, can meet the requirement of structure for bearing capacity under the prerequisite not increasing the rigidity of structure; (2) bearing capacity is high; (3) ductility and Hysteresis Behavior good; (4) can be used for protecting agent structure; (5) support tension and compression bearing difference little, can adjacent members be reduced stressed.The application of anti-buckling support, improves the anti-seismic performance of traditional support framework under middle shake and large shake.
Where all being born by the central layer be connected with other components suffered by traditional anti-buckling support, outer sleeve and packing material only provide the effect of constraint central layer compressive buckling, to ensure that central layer all can enter surrender under tension and pressurized effect, there is the shortcoming that power consumption form is single.
Summary of the invention:
For improving the energy dissipation capacity of traditional anti-buckling support, the invention provides the anti-buckling support of a kind of friction energy-dissipating formula.
For achieving the above object, design scheme of the present invention is as follows.The anti-buckling support of a kind of friction energy-dissipating formula, includes confining part 1, piston 2, power consumption core 3; Arrange piston 2 in the middle part of power consumption core 3, confining part 1 is enclosed within the surface of piston 2; Confining part 1 is fixed by end plate 4 and power consumption core 3 one end; Junction steel plate 5 is provided with at the two ends of power consumption core 3.
Described confining part 1 section form is square, rectangle or circle.
The quantity of described piston 2 is one or more, and the section form of piston 2 is consistent with the portion-form that the cross section of confining part 1 surrounds.
The in-line that described power consumption core 3 weakens for middle part or cross steel plate.
When structure generation relative storey displacement, power consumption core produces plastic strain consumed energy, to consume energy core and confining part generation relative displacement simultaneously, be fixed on consume energy piston on core and confining part generation relative motion, by the friction consumed energy of piston and confining part.
The present invention arranges piston in the anti-buckling support of tradition, introduces friction energy-dissipating mechanism, effectively improves the energy dissipation capacity of anti-buckling support.
